TYPESETTING MACHINE HAVlNG MEANS TO PROPERLY POSITION LARGER THAN NORMAL MATRICES Filed Nov. 27, 1964 5 Sheets-Sheet 3 United States Patent 12 claims. (ci. 19a-ss) The present invention relates to Linotype machines.

In particular, the present invention relates to that part of a Linotype machine which deals with the setting of the matrices so as to be able thereafter to cast slugs therefrom.

Conventionally, such a machine is provided with a rotary mold disk carrying a plurality of molds, and through a suitable control means the mold disk means is rotated so as to be angularly adjusted for properly situating the molds thereof.

One of the primary objects of the present invention is to provide a machine of the above type which is particularly adapted to cast slugs from relatively large matrices in an extremely simple manner.

Another object of the present invention is to provide a structure which is capable of bringing this result about through the use of one or more stops arranged on the vise of the machine and controlled in accordance with the position of the mold disk, these stops coacting with an elevator which carries the matrices so as to determine the proper level of the matrices carried by the elevator.

The matrices are normally situated in the elevator head at a selected one of a plurality of different elevations (such as a regular position or an auxiliary position), depending upon the particular characters which are to be cast, and these different elevations are provided for the conventional two-letter matrices. According to the Didot system, the two-letter matrices require an elevation difference of 5.556 m-m. In this system, however, when dealing with relatively large two-letter matrices, so called duplex display matrices, starting from a 16 point size, the elevation difference between the letters of a matrix is required to be 8.859 mm. This results from the fact that with conventional two-letter matrices, the situation thereof is 3.302 mm. lower. Thus, when casting slugs from these relatively large duplex display matrices, the elevator head and its carriage must be stopped during their downward movement 3.302 mm. earlier than with conventional matrices. Up to the present time, it has been required with machine for casting slugs from this latter type of relatively large matrix to manually control the movement of the elevator-controlling rail, so as to determine the limiting of the downward movement of the elevator, this rail having the stop of 5.556 mm. thickness fixed thereto, and in addition it has been necessary to bring about the turning of a further stop of 3.302 mm. thickness which after being turned onto the other stop of 5.556 mm. thickness provides with the latter the required total thickness of 8.858 mm.

In accordance with the present invention the duplex display matrices are initially assembled in the assembling elevator at the proper casting position, so that the auxiliary faces initially have the elevation displacement of 5.556 mm. when they are transferred into the elevator head. Thus, the stop of the present invention which is situated on the vise has a thickness of 3.302 mm. (all values being according to the Didot system referred to in the above example), and thus this stop means of the invention engages the assembled matrices .at the elevation which is proper for the casting of slugs from the auxiliary characters of two-letter display matrices of relatively large size.

For casting of slugs from relatively large single-letter matrices, up to 36 points, these matrices are normally assembled and then according to the invention controlled by a stop of 5.556 mm. thickness so as to be situated at the proper casting height.

For the casting of relatively large single-letter matrices of greater than 36 point thickness, the matrices are also assembled in the normal manner and then in accordance with the invention controlled by the stops of 5.556 mm. and 3.302 mm. (providing a total of 8.858 mm.) thickness, so as to be situated at the proper casting elevation.

Both of these embodiments of the invention provide faultless casting of a slug from these special matrices.

In all cases, the following serious problem is solved with the present invention. In the event that the elevator is suspended at too high of an elevation, which is to say the matrices are not situated at the proper elevation for faultless casting, then during the preliminary movement of the mold disk carriage, the ears of the matrices do not enter into the proper groove of the mold but instead engage the mold itself. If the elevator is suspended at too low of an elevation, then the mold will move into engagement with the elevator head carrying the line of matrices. Both of these improper elevations of the elevator will result in damaging of the above-mentioned components of the machine as well as other parts thereof which are situated in the train of transmission of the elements. If it should happen that subsequently to such an improper setting of the elevator the casting structure is actually released for operation, then there will be an extremely undesirable and unavoidable spraying of the hot casting metal to a location other than the interior of the mold.

With the present invention a positioning means determines the position of the molds carried by the mold disk, and it is this positioning means which forms a control means for controlling the actuation of the stop means which determines the position of the elevator. This arrangement provides the advantage of rendering the position determining means which is used for normal matrices also useful for the casting of two-letter relatively large matrices, so that a special control device is unnecessary.

Preferably, with the present invention, when casting slugs from the auxiliary characters of two-letter matrices of relatively large size, an auxiliary slide rail of the assembling elevator in which the matrices are assembled is moved into this elevator at the proper moment, and this action will initiate the actuation of the stop means which produces the result of determining the proper elevation of the elevator and the auxiliary faces of the duplex display matrices carried thereby. This arrangement also presents, among other advantages, the advantage of making use of structure which is already on hand, so that in this simple way the functioning of this latter structure is used for initiating the above-mentioned controls.

If it is desired to cast slugs from single-letter matrices of relatively large size, then in accordance with the further feature of the invention, the casting of this slug from these matrices takes place with the latter assembled in the normal position and the control of the actuation of one or more stops is carried out by a special controlling means.

Also, in accordance with an advantageous feature of the invention, the initiation of the control of the stop means is carried out in dependence upon the position of the matrix magazine by electrical contacts mechanically actuated from the magazine. In this way the range of utility of the invention is considerably widened and in particular the correct supply of the proper matrices for the proper molds is guaranteed in a simple manner.

Furthermore, it has been found to be of considerable advantage, in machines which are controlled by perforated tapes, to initiate the control of the stops of the invention by a particular combination of perforations of such tapes. Thus, it is basically possible in this way to provide remote controls, and the choice of a special combination of perforations guarantees the reliability and dependability of the control operation and guarantees the independence of other functions determined by particular perforation combinations of the same perforated tape. Moreover, by using the perforated tape control for actuating the slide rail of the assembling elevator in connection with the positioning means for determining the angular position of the mold disk, it is possible, without the use of a further combination of perforations of the tape, to provide for the casting of slugs from two-letter relatively large display matrices by actuating an additional stop.

Furthermore, in accordance with the invention, it is of advantage to connect the stop or stops of the invention with the conventional slide rail situated on the vise and to actuate the rail in opposition to a spring which urges it to return to a givenrest position. It is of 'advantage in this case, among other advantages, to provide an arrangement where the stop forms its function only as long as the adjusting force acts on the rail.

If the stop or stops of the invention are actuated by the positioning means for determining the position of the mold disk, then in accordance with the invention it is of further advantage to provide the actuation through electromagnets controlled by relays. This has, among other advantages, the advantage of providing a simple -actuation which can be easily observed and very well controlled.

Furthermore, it is possible to provide at the means which determines the position of the mold disk, additional switches actuated by special cams of the positioning means and controlling the circuits of one or more electromagnets. Such an arrangement is also simple and of advantage particularly because it requires only a relatively small change in the configuration of the positioning means which is in any event required.

In the case where the machine is controlled from a perforated tape, it has been found to be of advantage to locate in the circuit of the relays for the electromagnets which control the actuation of the stop and the rail connected thereto, a switch which is actuated by the slide rail of the -assembling elevator, this slide rail being controlled either by hand or by the perforated tape. Also with this construction considerable use is made of the part-s of the machine which are already on hand. This construction moreover provides in the simplest possible way a choice between automatic and hand operation.

It a plurality of slugs are to be cast simultaneously, then this result can be achieved very simply with the invention by providing in the relay circuit of the electromagnet or electromagnets a bridging contact, preferably a switch situated in the normal region of the machine which is available to the operator. This arrangement further widens the possibilities ilowing from the present invention while requiring only an insignificant expense.

With the `above objects in view, the invention includes, in a Linotype machine, a rotary mold disk means carrying a plurality of molds, as well as a vise having an upper portion and an elevator which is adapted to carry matrices of relatively large size. A stop means is preferably carried by the upper portion of the vise means for cooperating `with the elevator, and a control means controls the movement of the stop means in accordance with the position of the mold disk means so that the auxiliary characters of matrices carried by the elevator will be situated at the proper height for casting slugs from the matrices.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. rfhe invention itself, however, both as to its construction and its method of operation, together with addition-al objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings, in which:

FIG. l is a perspective illustration of that part of a Linotype machine which is provided with the structure of the invention;

FIG. 2 is a perspective illustration of the structure for controlling the slide rail of the assembling elevator;

FIG. 3 is a perspective illustration of the positioning means for determining the position of the mold disk; and

FlG. 4 is a wiring diagram of the machine.

Referring now to FIG. l, it will be seen that there is situated on the upper part It of the vise of the Linotype machine a conventional slide rail 2 which is shiftable in a direction parallel to the front face of the mold disk 3. The rail 2 is guided by a guide member 4 which is bolted to the vise. A stop means formed by a stop member 6 is xedly connected with the rail 2 -by an angle member 5. Tae stop e has a thickness of 3.392 mm. corresponding to the difference in height between the auxiliary character of a two-letter display matrix, and of a standard twoletter matrix, and engages an unillustrated stop screw situated in the only partially illustrated elevator carriage 7 for determining the elevation of the latter and of the auxiliary characters. The elevator head, which is also unillustrated and which is bolted to the elevator carriage, serves to receive the matrices, as already mentioned above, and the matrices are properly oriented in the elevator head without any gaps therebetween so that when cooperating with an also unillustrated mold carried by the mold disk 3 a slug will be cast from the matrices.

At the other end of the rail 2 is a two-armed lever 8 which is linked at one end to the rail 2 and which is turnably supported by a pin 9 which is fixed to the upper portion l of the vise. rfhe end of the lever 8 which is distant from the rail 2 is pivotally connected by a pin i0 with a head 1l to `which the pin itt) is fixed. The head 11 is connected to the pull-rod or armature 12 of an electromagnet 13 which is carried by a plate ld which is also fixed to the upper portion l of the vise. A spring l5 is coiled about the armature f2 and is `under compression to form a spring means which urges the rail 2 into its rest or starting position, and the rail 2, when it is moved, is of course moved in opposition to the force of the spring means l5.

In the same way, an additional magnet similar to the magnet i3 can be provided for actuating another stop through another rail similar to the rail 2, and this other stop, which is shifted, for example, can have -a different thickness (5.556 min). When this additional stop is combined together with the first stop (3.302 mm.), then there is a total stop thickness of 8.858 mm.

Arranged beneath the magnet 13 are a pair of relays` (indicated in the wiring diagram of FIG. 4 as the relays 16; and 16H), and the purpose and manner of operation of these relays are explained further below. An angle member i7 is bolted to the head il, and this angle member ll'7 serves to engage a roller i3 of a microswitch i9 for actuating the microswitch. Beneath the latter switch is an angle member Ztl which carries a push-button 21 which, when it is actuated, makes it possible in a manner described below to simultaneously cast a plurality of slugs from two-letter relatively large matrices.

With the rail switching structure for large matrices shown in FiG. 2 for the assembling elevator 22, the auxiliary slide rail 23 in the assembling elevator is actuated by a bar which is pivotally connected at 25 to a T-lever 26, this pivotal connection also being yieldable inasmuch as it includes a spring and a pin-and-slot connection as indicated in FIG. 2. The T-lever 25 is pivoted at 27 to the partially-illustrated lever 28, and through a pair of links 29 and 30, the lever 26 is connected with a further lever 31 which is pivotally connected at 32 to the lever 28. The lever 31 is provided with a detent roller 33 which is capable of being received in the recesses of a detent bar 34. The lever 28 is fixed to a shaft 35 and is coupled with the assembling elevator 22 by the bar 36. By means of an unillustrated lever which is xed to the shaft 35, the assembling elevator 22 can be raised by the lever 28. The lever 28 fixedly carries a switch support 37 which carries a microswitch 38. If the lever 31 is moved by hand or by a device 100 controlled by a perforated tape 102 from the position shown where the detent roller is received in the right detent recess 39 to a position where this roller is received in the left detent recess 40 of the detent bar 34, then at the same time the link 29 and the link 30 will operate to turn the lever 26 downwardly. Device 100 has a conventional head 161 for reading out perforations in tape 102, and operates a shaft 163 carrying a lever 104 operatively connected with lever 31, as indicated by a broken line 165. As a result the bar 24 is pulled downwardly, so that the angle member 41 shifts the auxiliary slide rail 23 into the assembling elevator 22 for assembling the matrices in the casting position for relatively large display matrices, particularly duplex display matrices. The link 29 is shifted forwardly, as a result of this actuation of the lever 31, and as a result an angle member 42 carried by the link 29 engages and actuates the microswitch 33.

The position-determining means shown in FIG. 3 for determining the position of the mold disk 3 is indicated at its entirety at 43 and is arranged on the box-'like part 44 of the base plate 45 of the structure for adjusting the angular position of the mold disk 3. The plate 4S is connected in an unillustrated manner with the left bearing support of the main shaft of the Linotype machine. The positioning means 43 includes a switch plate 46 which is bolted to the box-like part 44. In front of the switch plate 46 is a cam disk 47 which is provided with a lobe 48. This disk 47 is mounted on the end 49 of a worm wheel shaft which is not further visible, and this worm wheel shaft is driven by a worm t) which also is only partly visible. The worm shaft 5t) carries a pulley 51 which is driven by means of a belt 52 from an unillustrated flywheel brake motor.

The switch plate 46 carries, around the disk 47, four microswitches 531, 532, 533, 53.1, corresponding in the illustrated example to the four molds carried by the mold disk 3. The conductors for these switches are situated in tubes and extend to la porcelain insulator 55. In addition to the microswitch 53.1, there is a further microswitch 56 which is actuated by an angle member 57 carried by the cam disk 47. The angle member 57 can be ixed to the disk 47 in four different positions according to the selected one of the four microswitches, these po-ssible positions of the .angle member 57 being displaced with respect to each other in the same way Ias the distribution of the four microswitches 53153.1. The cam lobe 48 actuates, in the illustrated position, the microswitch 532, s-o that at this time the angular adjustment of the mold disk has terminated. In this way the mold which corresponds to the microswitch 532 h-as been positioned for the next-following casting cycle, assuming that this latter mold was selected before the angular adjustment of the mold disk.

When the microswitch 56 is closed by the angle member 57, this microswitch 56 closes the circuit of the electromagnet 13 which actuates the stop means 6.

From the wiring diagram of FIG. 4 the construction and operation of the electrical connections of the invention are apparent. The relays 161 and 1611 are shown with their operating contacts r11, r12, r111 and r112, the latter contacts of course being part of and controlle'd by the relay 1611, while the contacts r11 and r12 are controlled by the relay 161. The relay coils are connected on one side to the positive pole of a source of direct voltage, and the electromagnet 13 is also connected to this positive pole.

The circuit for the relay 161 is closed by a switch 58 of the assembling elevator 22, this switch 58 not being shown in FIG. 2, as well as by the microswitch 38. A further switch which is not illustrated in FIG. 2 has a normally closed contact c3 and a normally open contact c2, this latter switch being actuated upon transfer of the line of matrices into the first elevator which also is not illustrated. The normally closed switch e serves as an end switch which is actuated upon upward movement of the elevator carriage 7 (FIG. l) after casting. The contact of the microswitch 19, also indicated in FIG. 4 (see also FIG. l), this microswitch acting as a control switch, is actuated upon excitation of the electromagnet 13.

The push-button 21 of FIG. 1 when actuated by the operator, serves to close the normally open switch 59 shown in FIG. 4. This switch is connected together with the end switch e and the microswitch 19 in the circuit of the relay 1611.

The switch 56 (see also FIG. 3), when it is closed, serves to close the circuit for the electromagnetic actuation of the stop means 6 of FIG. l.

The switches and contacts 38, 58, c3, c2, e, 19, 59 and 56 are all connected to the negative pole of the source of voltage.

The control of the actuation of the stop means 6 is initiated with shifting of the slide rail 23 in the assembling elevator 22, and this operation is brought about either by means of device under the control of a perforated tape 102 or by hand through actuation of the lever 31 (FIG. 2). Actuation of the lever 31 or a control by the perforated tape will close the microswitch 38. When the line of matrices assembled in the assembling elevator 22 are placed in the proper position for transfer to the rst elevator by raising of the elevator 22, the switch 58 is closed. As a result the relay 161 is energized and this relay will remain energized through its holding contact r11 and through the normally closed switch c3. At the same time the contact :'12 is closed in preparation for closing the circuit of the relay 1611.

Upon transfer of the line of matrices into the rst elevator, an unillustrated transfer switch is actuated for a shore period of time, so that the working contact c2 is closed and thereafter the normally closed switch c3 is opened. The relay 1611 is energized, and thereafter the relay 161 becomes deenergized and is free to receive a new signal from a suitable control.

The relay 1611 remains energized through its working contact r111 and the normally closed end switch e, and at the same time the circuit for energizing the electromagnet 13 is ready to be closed by the closing of the contact 1'112.

By adjusting the angular position of the mold disk 3,

a predetermined mold is placed in proper position for casting a slug from the matrices. According to the positioning means illustrated in FIG. 3, that mold which corresponds to the microswitch 532 is the mold which is in this casting position. Upon actuation of the switch 532 by the cam 48 of the disk 47, so as to terminate the angular adjustment of the mold disk, the microswitch 56 is also actuated by the angle member 57, so that the circuit for the magnet 13 is closed, and the energizing of the magnet 13 will, as is apparent from FIG. l, shift the stop means 6 (5) to the right through the transmission elements 12, 11, 10, 8, 2. The stop means has thus reached the position in which it will determine the proper elevation of the carriage 7 of the rst elevator so as to position the latter at the proper location for casting of a slug from the two-letter relatively large matrices.

The normally closed switch 19 opens upon energizing of the magnet 13 (see FIG. 1), so that after the subsequent casting and opening of the normally closed end switch e, the relay 1611 will again become deenergized aangaan upon upward movement of the elevator carriage 7. The switch 19 serves to provide a control by bridging the end switch e long enough to maintain the relay i611 energized until the electromagnet i3 becomes energized.

For simultaneously casting a plurality of slugs, the end switch e and the control switch 19 can be bridged by actuation of the push-button 21 and closing of its switch 59. The relay 16H and thus the electromagnet 13 remains energized as long as the hand switch is manually maintained closed.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of Linotype machines differing from the types described above.

While the invention has been illustrated and described as embodied in matrix setting and slug casting structures, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any Way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
